Project description:Previous reports of simultaneous presence of esophageal varices (EV) and achalasia suggest placement of a transjugular intrahepatic portosystemic shunt (TIPS) and surgical myotomy or endoscopic therapy. We report the case of a 64-year-old man who received anticoagulant therapy for a myeloproliferative disorder with extensive portal thrombosis which was a contraindication to placement of a TIPS. .
Project description:Phasic coronary artery compression is typically associated with spasm or myocardial bridging. Compression caused by acquired anatomic changes to the surrounding heart chambers has been reported only infrequently. We present a possibly unique case of phasic compression of the proximal left circumflex coronary artery during atrial contraction in association with a dilated left atrium. A 55-year-old man with multiple cardiac risk factors presented with worsening exertional dyspnea. An electrocardiogram and echocardiogram revealed marked left atrial dilation and a left ventricular ejection fraction of 0.15 to 0.20 with elevated filling pressures. Angiograms showed compression of the proximal segment of the left circumflex coronary artery during late ventricular diastole: the compression occurred in phase with atrial systole, whereas good flow without compression was present during atrial diastole. We attributed this phenomenon to ballooning of the lateral region of the atrial wall toward the atrioventricular groove during atrial systole. The patient complied with antihypertensive therapy, and his status improved after one year. To identify coronary artery compression in the presence of abnormal chamber geometry and to guide the treatment of the contributing medical conditions, we recommend careful analysis of angiographic results.
Project description:Left atrial-esophageal fistula (LAEF) is a rare complication of radiofrequency ablation (RFA) procedures undertaken for atrial fibrillation (AF). This complication is associated with significant morbidity and mortality. Currently, there is no clear consensus on the appropriate management strategy. We report a case of a LAEF that developed in a patient 2 weeks after RFA for medication refractory AF. The patient underwent successful repair of the fistula through a left posterolateral thoracotomy, wherein the esophageal and atrial lesions were repaired primarily with an intercostal muscle flap and bovine pericardial patch to reinforce and prevent recurrence.
Project description:Esophageal achalasia is a primary motility disorder characterized by insufficient lower esophageal sphincter relaxation and loss of esophageal peristalsis. Achalasia is a chronic disease that causes progressive irreversible loss of esophageal motor function. The recent development of high-resolution manometry has facilitated the diagnosis of achalasia, and determining the achalasia subtypes based on high-resolution manometry can be important when deciding on treatment methods. Peroral endoscopic myotomy is less invasive than surgery with comparable efficacy. The present guidelines (the "2019 Seoul Consensus on Esophageal Achalasia Guidelines") were developed based on evidence-based medicine; the Asian Neurogastroenterology and Motility Association and Korean Society of Neurogastroenterology and Motility served as the operating and development committees, respectively. The development of the guidelines began in June 2018, and a draft consensus based on the Delphi process was achieved in April 2019. The guidelines consist of 18 recommendations: 2 pertaining to the definition and epidemiology of achalasia, 6 pertaining to diagnoses, and 10 pertaining to treatments. The endoscopic treatment section is based on the latest evidence from meta-analyses. Clinicians (including gastroenterologists, upper gastrointestinal tract surgeons, general physicians, nurses, and other hospital workers) and patients could use these guidelines to make an informed decision on the management of achalasia.
Project description:The diagnosis of idiopathic dilatation of pulmonary artery is challenging because its clinical recognition is difficult and various other causes of dilated pulmonary artery need to be excluded. The clinical findings mimic various common cardiac disorders and both invasive and non-invasive investigations should be done to arrive at the diagnosis. It is a known clinical entity but etiology and pathophysiology are largely unknown. The current echocardiographic and catheterization based diagnostic criteria, may not be satisfied completely in a particular patient and need to be revisited in view of newer imaging modalities. There is paucity of information about the natural history of the disease with attendant lack of clarity in treatment guidelines. Certain cases may progress to huge dilatation and consequent serious implications. It is a rare disease and is the diagnosis of exclusion.
Project description:Background?:Left atrial appendage (LAA) closure with the WATCHMAN device is an alternative to anticoagulation therapy for the prevention of stroke in selected patients with atrial fibrillation (AF). Infrequently, left atrial (LA) device-related thrombus formation occurs and it is poorly understood. Thrombus formation due to incomplete covering of the LAA is even rarer and may occur within the first few months after device implantation. Case summary?:Here, we present a case of a 68-year-old male patient with permanent AF, drug- and hepatitis induced liver cirrhosis (CILD Score B), and prior aortic valve replacement. The patient had a history of percutaneous LAA closure using a WATCHMAN device. He developed massive peri-device leak and thrombus arising from the space between the device and appendage cleft 2 years after implantation. Because of the high bleeding risk with a HAS-BLED score of 5 points, surgery was chosen as the therapy of choice instead of long-term anticoagulation. The patient was discharged in good clinical condition and has been scheduled for a yearly follow-up. Discussion?:This case emphasizes the importance of choosing appropriately sized LAA occluder devices and planning for regular post-interventional follow-ups to minimize the risk of per-device leaks and thrombi.
